She said, thankfully, she and fellow designer Brendan Courtney weren't there to see the dispute, as "that would have been a bit embarrassing".

Amy contacted them last week to inquire about the one-piece.

"She saw it online before they went into the store and we were able to help her out with it. It only went up there and into the stores on Saturday, and we think there's only a couple left now," she said.

Actress Amy, who has spent the past two weeks in LA, posted a snap of herself jumping in the outfit, saying: "Hey Lennon-Courtney, your jumpsuit has been tried and tested, and totally works! Thank you."

Also at the Hollywood bash was Claudine Keane and Indiana Jones actress Alison Doody.
